POURlNG-NOZZLE FOR SHEET-lWE TAL CANS.

SPECIFICATION forming part of Letters Patent No. 437,231, dated September 30, 1890.

Application filed March 10, 1890.

- difierentpieces, it has usually been necessary or customary to solder many of thepieces to gether by hand, so that the nozzles are of a comparatively expensive construction.

The object of my invention is to producea pouring-nozzle and cap for closing the openin g in the can through which it is filled of a simple, strong, efficient, and durable construction, the difterent pieces or parts of which may be cheaply and rapidly made by machin:

cry and assembled or put together without solder.

To this end the invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which simi-j lar letters of'ret'erence indicate like parts,

Figure l is a side elevation of a device em bodying my invention, the can to which it is applied being indicated in section. Fig.- 2 is an enlarged sectional view of the pouring nozzle. Fig. 3 is a plan view showing the upper plate or disk of the nozzle with the valve screw, thumb-piece, and spout removed. Fig. 4 is a side view of the spout. Fig. 5 is a detailplan view of the thumb-piece with its upper or covering disk removed. Fig. 6 is a plan view of the washer. Fig. 7 is a section on line .7 7 of Fig. 6.

In the drawings, A represents the can,and

A the upper head or cover,having the opening A through which the can is filled. The opening A is surrounded by .the usualV- shaped cap-groove a to form a scatter the nozzle or cap disk B, which is soldered in place Serial No. 343,240- (No model.)

therein. The nozzle or cap disk B is provided with the valve-opening B, which is closed by the Valve C. The valve-seat b is formed by turning in the annular edge of the disk B, surrounding the opening B. It is clearly shown in Fig. 2. The valve C consists of an oval disk of cork or other suitable material supported on a metal disk C, having a flange or edge 0 turned over the cork disk, so as to em brace and secure the same. The valve-disk C is furnished with a centralhole 0, through which the valve-stem D is inserted, and secured by soldering. The valvestem D is screw-threaded and works in the threaded nut D, which is secured between the upper ordome disks F F of the nozzle. The dome or bridge disks F F of the nozzle are one or both, preferably both, furnished with countersinks or pockets f to receive the nut D. The countersinks or pockets f f correspond to the nut in outline, so that they serve to hold the nut from turning and to fixit readily and securely in place.

The dome or bridge disks F F are securely clamped together, and at the same time united to the cap or valve-seat disk B by folding or crimping the flange of one of the disks over the other two, preferably the flange or edge I) of the disk B over the two dome-shaped plates or disks F F. The flange, crimp, or fold b,by which the three plates or disks F F B are readily united together, may be formed in any suitable manner or by any suitable means.

H is the pouring-spout. It consists, preferably, of a short cylindrical tube having its ends cut at an angle about as shown in the drawings. The lowerend of the spout is furnished with a flange h, the plane or surface of which is or should be curved to fit the curvature of the upper or bridge disks F F of the nozzle. The spout is secured in place by inserting its flange it between the domedisks F F, so it will be clamped and held rigidly between them, one of the disks, and preferably the lower disk F, being provided with a countersink f to receive the flange of the spout.

Owing to the curved or spherical form of the disksF F and to the elliptical outline of h, the spout is rigidly locked and held in place, so that it cannot turn. The side seam h of the spout is preferably soldered. It will of course be understood that the nut D, as well as the spout H, is inserted in place between the plates or disks F F before said disks are secured together by folding or seaming the flange b of the disk B over the same. The disks F F are provided with a vent f K and K are the thumb-piece disks by which the screw-threaded valve-stem D is turned, and K is a washer embraced between the disks K K and to which the shouldered or offset end (Z of the valve-stem is riveted. The washer I is preferably of rectangular form, and is provided with a rectangular countersink 76, into the corners of which the quarters of the divided end of the shouldered valve-stem are bent or riveted, so as to prevent any possibility of the valve-stem turning in the washer K and whereby the valve-stem is rigidly and firmly secured to the washer. The lower thumb-piece K is furnished with a hole 7a, through which the oifset end (1 of the valve-stem is inserted, so that the disk K may rest upon the shoulder at of the valve-stem.

The rim or edge of the disks K K are formed into a roll k, and the outer surface of the roll is milled or knurled. to afford a bearing for the thumb. The roll k serves also to bind and clamp the two disks K K rigidly and firmly together and the washer K between them. The upper thumb-disk K is furnished with a countersink 70 corresponding to the washer K to prevent the washer turning in respect to the disks and to fix the washer rigidly in place.

The opening in the outer dome-disk F to receive the spout should be slightly oval or elliptical to correspond to and properly receive the end of the spout H.

N is a ring of sheet solder folded over the rim of the cap or nozzle-disk B for use in soldering said disk in the cap groove or seat a of the can-top, and simultaneously uniting or soldering together the plates 13 and F F.

The several parts of my combined can-cap and valved pouring-nozzle, it will be observed, are rigidly and tightly secured and combined togetherwithout the use of solder, with the single exception of the solder used to unite the valve-stem D to the valve-disk C, and for this reason I am enabled to make, assemble, and secure together the various parts very rapidly and cheaply, and at the same time I produce a much stronger, neater, better, and more durable valved pour-out nozzle than those heretofore generally in use.

I claim- 1. In a valved pouring-nozzle for cans, the combination of a valve-seat disk 13, a valve 0, a threaded valve-stem D, a nut D, a pair of demo or bridge disks F F, a spout H, having flange h, said nut D and the flange of said spout being embraced and clamped between said disks F F, and said disks F F being secured together and to said disk B by a flange or fold b on said disk B, substantially as specified.
